7 Claims. 1

My present invention; in its broad aspect, has reference to improvementsin simple; effective and practical means for lowering automobilewindows, and is tobe used in conjunction with conventional gear.mechanism, and the like, for raising an automobile window"; ordinarily,it is desirable to more quickly lower a window than it is to raise awindow since, among other'things, on approaching an inter-section,slowing up, or making a turn, it is required that a hand signal begiven. Also in regulating the extent which a Window is opened, itis-usually opened wide and then gradually closed to the extent desiredfor proper and comfortable ventilation. My invention contemplates theuse of compressed air means for actuating the window operating quadrantduring the openingcycle and releasingthe usual lever actuating pinion,and then re-engaging the usual lever actuating pinion and discontinuingthe compressed air means on the closing cycle so that the usual meansmay be employed in closing the window. The compressed air to operate mydevice may be supplied from a compressed air tank refillable at anygasoline filling station, or may be supplied by a small pump connectedWith a power take-01f from the fan belt.

My invention may be applied with little modification to conventional carbody and window construction, and is simple and sturdy and has nofragile or intricate parts which are likely to get out of order or to bederanged or broken in use.

Other and equally important objects and advantages of my invention willbe apparent from the following description and drawings, but it ispointed out that changes in form, size, shape, materials, constructionand arrangement of parts is permissible and within the purview of mybroad inventive concept and the scope of the appended claims.

In the drawings, wherein I have illustrated a preferred form of myinvention:

Figure 1 is a side view of the assembly as applied to a conventional cardoor, and

Figure 2 is a view of a modification of my device.

In the drawings wherein like characters of reference are used todesignate like or similar parts throughout the several views:

The numeral l designates a conventional type of automobile door or body,having the usual sliding glass window 2, in a frame 3. A conventionaltoothed quadrant 4 is pivoted at 5 and has a lever 6 which is pivoted tothe quadrant as at land which raises and lowers the window when thepinion 8-in mesh with the teeth of the quadrantis turned by a handle oroperating lever (not shown).

According to my invention, the lever Bis extended as at 9, and a secondlever lll--similar to the lever 6is pivoted to the quadrant as at H andis extended as at l2 and pivotally connected at It to the extended endQ-oflever 6'. The pinion B ismounted on the circular enlargement [4between the arms [5- and [Got a bell-crank lever ll, one arm l6 of whichis pivoted to the door asat l8. To the other arm [5 of the bell-cranklever I! is pivoted a link I9, pivotally connected as at 26, to apivoted arm 2| on the door. A spring 22 normally pulls the arm forward,and a link 23 pivoted to the arm 2| slides in the keeper 24 and engagesa cam 25 on the handle 26. The handle 26 is connected with a valve 2'!to open and close connections 28 and 29 between a compressed air pipe,the connection 29 of which leads to a compressed air tank 30, and theother connection 28 of which leads to a cylinder 3|. The compressed airtank 30 has a filling nipple 32 to recharge the tank at any gasolinestation air line when desired. The cylinder 3i is pivoted at one end asat 33 and has a piston 34 with an adjustable rod 35 adjustably andpivotally connected to the lever ID as at 36.

Under ordinary circumstances, to raise the window, the pinion 8 isrotated by a suitable handle (not shown), but to lower the window, thehandle 26 is moved to disengage the pinion 8 from the quadrant 4 and toestablish communication through valve 21 between compressed air tank 30and cylinder 3| whereupon piston 34 is moved to move the quadrant 4 andlevers 6 and Ill to quickly and easily open the window. The action ofthe piston is cushioned by a body of compressed air at the oppositesides of the piston and a bleed opening 31 is provided to permit itsoperation. When the window has been opened, the handle 26 is moved tonormal to re-engage the pinion 8 with quadrant 4 to permit raising thewindow in the usual manner.

In Figure 2, a push pin 38 is substituted for the handle 26, and ismounted in brackets 39 and has a spring 40 for normally moving the sameupwardly. A pair of cams 4| and 42 engage respectively a valve operatingrod 43, and the slide plate 44 carrying the pinion 8. The rod 43 ismounted in brackets and has a spring 45 to move it against the cam 4|,and the plate 44 has an arm 46 with opposed rollers 41 and 48 betweenwhich cams M and 42 operate to move the plate 44 which has opposedvertical supporting arms 49 slidably mounted in keepers 50. By thisstructure, downward movement of the push pin 38 retracts the plate 44 todisengage pinion 8 to release quadrant 4 and open the valve 21 to lowerthe window by .operation of the piston by compressed air, and raising ofthe pin by spring 40, closes the valve 21 and re-engages the pinion 8with the teeth of the quadrant for normal operation in closing thewindow.

From the foregoing, it is believed that the operation and advantages ofmy invention will be apparent, but it is again emphasized thatinterpretation of its scope shall only be conclusive when made in thelight of the subjoined claims.

I claim:

1. A window opening device for use with an automobile window having anoperating pivoted toothed quadrant, and a pinion for operating thequadrant to close the window, comprising a movable mount for the pinion,a source of compressed air, a cylinder and piston assembly, a lever onthe quadrant, a rod connected with the lever a second lever on saidquadrant pivoted to said first lever, said second lever pivoted to saidwindow for the raising and lowerin thereof said first rod connected tosaid cylinder -and piston assembly, a valve in the compressed air linefrom the cylinder to the source of compressed air, actuating meansoperatively connected with the valve and with the movable mount for thepinion to release the pinion from the quadrant when the valve is opened,and to re-engage the pinion when the valve is closed.

2. The invention as defined in claim 1 wherein the cylinder has a bleedopening, the levers are connected with each other at an angle, and thepiston rod is connected with one lever and the window with the other.

3. The invention as defined in claim 1 wherein spring means are providedto return the pinion to a position in engagement with the quadrant, andwherein the source of compressed air includes a compressed air tank.

4. The invention as defined in claim 1 wherein the valve and pinionoperating means includes a pivoted handle.

5. The invention as defined in claim 1 wherein the valve and poweroperating means includes a slidable pin, and a spring for returning thepin to its normal starting position.

6. The invention as defined in claim 1 wherein the operating meansincludes a pivoted handle, a cam on the handle, and relatively connectedlinks and levers connected with the pinion and engaged by the cam, and aspring for returning the levers to normal position.

7. The invention as defined in claim 1 wherein the pin is provided witha pair of cams operatively associated respectively with the valve andwith the pinion, and wherein the piston has an adjustable piston rod.
